request for some help with performance and sound

[Patrick McKnight]

Richard,

Thanks for the quick reply and sorry about excluding relevant information.

I am using 7.10 (Gutsy) now.  The install is the AMD64 version on my server
and I boot off a i386 image for my clients.

With respect to the drivers and kernel, yes, I suppose the via driver
changed from the Dapper ltsp install to the Gutsy Edubuntu ltsp install.  I
would not expect the driver to account for the extreme difference but
perhaps that is the case.
